Which basically proves Lance Cavener's theory wrong.

I've also seen this (and some other minor oddities) under FreeBSD.
Seems the PCnet chips is quite more crippled than the original Lance
Am7990 chip.  This is however not surprising if you compare this with
other recent chip designs like 3Com's 3C5x9 and 3C59x which are
explicitly marked as ``for client use''.

Nevertheless, the chip was basically working for me, too.  (I had to
setup an environment that allowed duplication of 800 MB IDE drives
between HP Vectra's without disassembling the machines first.  The
sustained data rate were between 700 and 750 KB, but remember, the IDE
was used in PIO mode only.)
